The ratio of Country albums to Jazz albums in a music collection is 2:3. If the music collection has 45 albums, how many Country albums are there?

If there are 45 albums the answer has to be 30 to 45 albums divide 45 by 3 you get 15, multiply 2 by 15 and 3 by 15 and you have your answer. :)

2:3...added = 5 2/5(45) = 90/5 = 18 country albums <== 3/5(45) = 135/5 = 27 jazz albums
